Besides, the point that was obviously lost on Ray is not that I will be able to make me own computer, but that even our most advanced technology is nothing more than sand and oil and metals taken from our very surroundings. It isn't some mysterious object handed down from a mysterious race, WE made it, with OUR own ingenuity. And it wasn't as if though we said "me lack computer, me need figure out build computer." It was thousands of years of tinkering around with everything we found laying around, seeing what it could do, what it was made of, being curious about our surroundings. This same curiosity and ingenuity has not been lost. Put man in the situation I have described and he will not perish, he will flourish, and much more he will have FUN doing so.
